Abstract
A bus monitoring device includes a detector to detect a signal on the bus. The signal is initiated by one of a plurality of devices coupled to the bus. A clamp circuit is included to clamp the signal to a first predefined level in response to the signal being initiated by a first device of the plurality of devices. A comparator circuit compares the signal and a voltage reference to determine whether the first device initiated the signal.
